Statement and Declaration.

Patented June 4, 1907.

Application filed September 4, 1906. Serial No. 333,051.

To @ZZ 'wh/0m it nfl/tty concern:

Be it known that I, JOSEPH D. MrroHrLL, a citizen of the United States,residing at Apopka, county of Orange, State of Florida, have inventedcertain new and useful Improvements in Non-Refillable Bottles, of whichthe following is a full, clear, and eXact specification.

My invention relates to a non-reiillable bottle, and has for its objectto provide said bottle with simple and inexpensive means whereby, afterthe contents of the bottle have been withdrawn, the same will beeffectually sealed against the admission of any further liquid, andlikewise the provision of means whereby the admission of liquid to takethe place of that which may be withdrawn from the bottle from time totime is prevented; and particularly my invention consists in a pistonwhich is situated within the body of the bottle and underneath theliquid therein contained, and which will move up as the liquid iswithdrawn, so that the remaining portion of the liquid shall alwaysremain at the upper part of the bottle and may not be forced down, andto devices for preventing the downward movement of said piston. ,i

My invention also relates to sundry other features of construction fullyshown in the accompanying drawings, wherein Figure 1 is a verticalsection of part of a bottle equipped with my invention; Fig. 2 avertical section showing the piston in operation, Fig. 3 a plan view ofa spring used to maintain the piston in position, showing the bottle insection; Fig. 4 a horizontal section showing the bottom of the bottle inplan; Fig. 5 a horizontal section showing a modiiication of myinvention;Figs. 6 and 7 are detail views showing locking ring and slotted diskused to prevent the insertion of tools in the bottle. Fig. 8 is a detailsectional view of part of the modification of Fig. 5. Fig. 9 is avertical section wherein the modification of Fig. 5 is employed, andFig. 10 is a detail vertical section of the bottom enlarged for thepurpose of showing a leaky connection of the bottom through which airmay be admitted.

In carrying out my invention, a bottle 1, is preferably formed with aseparate bottom 2, which is united to the bottle by means of screwthreads, and is equipped with a series of thumb holes 3, for the purposeof easy insertion. Upon the inner surface of this bottom are containedtwo upwardly projecting studs 4, having ears 5, which project towardeach other, the purpose of which will be presently explained.

A circular disk 6 is provided, which forms a piston and is equipped witha packing 7, which may be formed of rubber or other suitable material,which will effectually seal the piston and will not contaminate thecontents of the bottle. This packing 7 is formed with an internalgroove, which receives the periphery of piston 6. Above the piston thepacking projects but a short distance, and as this surface of the bottleis wet by the presence of the liquid therein, no obstruction is offeredto the upward movement of the piston. The packing has an enlargedportion constituting an annular ring 8 formed in it below the piston 6,and upon an attempt to move the piston downward, the said enlargement 8will pinch upon the dry sides of the bottle and crowd up under the edgeof the piston 6, and eifectually lock the said piston against downwardmovement. Within the said annular ring 8, a diaphragm 9 is formedintegrally with the said packing which lies on the under side of thepiston, and in turn forms a packing to prevent the passage of the liquidthrough openings made in the piston for the passage of headed bolt 10,and bend 13 of spring 12.

A ring 11, is suitably attached to, or formed upon the piston 6 a -shortdistance inside of its periphery, and is dished outward so as to touchthe sides of the bottle and maintain the said piston 6 in a properhorizontal position and prevent one side from proceeding in advance ofthe other. This ring may be made in one piece as shown, or it may bemade of several small pieces. Between the said piston 6 and the bottomof the bottle is placed a helical spring. 12, the upper convolution ofwhich has a rectangular bend at 13, which passes through the diaphragm9, and is received in a hole in the piston 6. The bottom convolution ofthe said spring rests upon the bottom of the bottle, where it may beheld in position if desired. The strength of this spring is such that itshall be sui-licient to support the column of liquid above it, and Owingto its shape it has a gradually diminishing strength as it is forcedupward and in turn is required to support a diminishing column ofliquid, so that if any quantity of liquid is poured kout of the bottle,the piston 6 will be forced IOO IOS

IIO

upward under the action of the spring suiiiciently to bring the liquidup to its proper position in the neck of the bottle.

The headed bolt 1() carries at its bottom a pin 14, which projects uponeach side sufficiently to pass under the ears 5, formed integrally inthe bottom of the bottle, and before the bottle is filled with liquidthe sai d pin will be passed under said ears and hold the piston 6 inthe position illustrated in Fig. 1. Upon each side of the bottom of thebottle and close to the said ears are formed integrally studs 15, whichproject upwardly from the bottom of the bottle, and in the path ofmovement of the said pin 14. This pin 14 is made of some material whicheasily becomes fractured or bent. Therefore, a revolution of headed boltin a clockwise direction (Fig. 4) will cause pin 14 to pass out fromunder the ears 5, and engage studs .15, whereby the said pin 14 will bebroken off or bent so as to permit the free vertical movement of thepiston, and it is obvious that should the said piston be forced downagain, the pin 14 may not be replaced under the ears 5. Figs. 2 and 9illustrate thesaid pins 14 as broken or bent, while Fig. 1 illustratesthem in position under ears 5 prior to breaking. The destruction of thesaid lock Will be performed by an authorized person, and the situationof the studs 15 is such that the pin 14 Will be broken off or bent sothat no further locking can be effected between those parts.

At the upper part of the bottle the same is formed with an annular bead16 forming an internal circumferential groove, against the walls ofwhich the packing 7 locks at the completion of its upward movement, andthe lower wall of which eifectually holds the same against any downwardmovement.

In the lower part of the neck of the bottle I have shown adisk 17 havinga circumferential groove adapted to receive the split spring ring 18.This ring being placed around the said disk. 17 and forced down in theneck of the bottle will sprin out in the groove formed in the bottlenec( at 19 and effectually lock'the said disk in place. The disk hasformed in it liquid passages at 20, which are inclined relatively to thehorizontal faces of the disk and are designed to prevent the insertionof any tools which might be intended to tamper with the piston 6. Ifpreferred, the said liquid passages might be tortuous in shape, orV-shaped, or of any shape which will properly and effectually preventthe insertion of tools, while freely permitting the passage of liquid.

A modified form of my invention is shown in Figs. 5 and 9, wherein,instead of permitting the spring 12 to rest directly upon the bottom ofthe bottle, and instead of equipping the said bottle with the inwardlyprojecting studs 4, I have provlded a separate bottom disk 21, a portionof which is pressedy downward as in Fig. 9, forming two anges or lockingprojections 28, which are adapted to enter rectangular recesses 23 inthe bottom 2, to provide against the rotation of the disk 21. This disk21 will lie immediately under the spring 12, and has a central raisedboss 29 in which is formed at 24 a slot through which may be passed thepin 14. Likewise formed on the under side of the said disk 21 are twopins 25, one of which is shown in Fig. 9, which project downwardlytherefrom, and which, upon a rotation of the headed bolt 10, will breakoff or bend pin 14. As shown in Fig. 5, bolt 10 will be revolved in aclockwise direction to bend or break off pins 14, but in this form of myinvention the bolt 10 may be revolved in either direction to break offor bend said pins.

If desired, instead of having the lugs 28 integral with disk 21,separate lugs 22, as shown in Figs. 5 and 8, may be provided andsecurely held in said disk.

In Fi 10 I have illustrated a manner in which t e bottom 2 may be heldin lace, while air will be admitted to permit of t e upward movement ofthe piston. It is intended that the said bottom will be held in place bya suitable cement, applied at suitable intervals to the screw thread,and that air may pass through the point where the cement is omitted.Accordingly I have shown the cement in place at 26, and at 27 isillustrated a section of screw thread from which the cement is omitted.The space between the male and female screw threads here is exaggeratedfor clearness of illustration.

The manner of assembling the bottle e uipped with my invention 1s asfollows: The piston 6 with guiding rin attached has inserted upon itsperiphery t e packing 7, and the headed bolt 10 is then -passed throu hthe said piston, and the pin 14 attache. Sprin 12 is then attached tothe said piston by end 13 and to the separate bottom of the bottle bypassing pins 14 under ears 5, and the piston and bottom being thenconnected, are inserted in the bottle. The bottom has had applied to ita slight amount of proper insoluble glass cement at several points inits circumference and it is screwed in place, the headed bolt 10revolving in unison with the bottom. Care should be taken that thebottom 2 is not sealed air-tight to the bottle 1, as it is desirable toprovide a leaky joint here, so that air may freely enter for the pur oseof facilitating the upward movement of t e piston and preventing theformation of a vacuum. A leaky joint is better for this purpose than itwould be to perforate the bottom 2, as such erforation would facilitatethe insertion o a tool to pull the piston down. Li uid is then pouredinto the bottle and it is ed up to a proper height, after which a screwdriver or suitable tool is in- IOO IIO

serted through the mouth of the bottle and the headed bolt 10 revolveduntil the pin 14 is removed from under the ears or disk 21, and in sodoing the said pin 14 will be broken off or bent so as to be useless,and the piston 6 is then released. This turning of theheaded bolt 10will be done by an authorized person, whose duty it will be to see thatthe pin 14 is broken oif so as to prevent a subsequent use. Split ring18 and disk 17 are then inserted and looked in the position shown in Theusual cork and cap, as illustrated in Fig. 2 may then be inserted.

All parts which come in contact with the liquid should be made ofmaterial which will not'contaminate it, and to this end the disk 17should be formed of glass porcelain and split ring 1S of aluminium, asshould also the piston and its guiding liange 1 1, as well as the headedbolt 10. The packing and diaphragm, I propose to make of rubber. Spring12 and lower disk 21 are not supposed to come in contact with theliquid, and therefore may be made of any cheap suitable material.Aluminium may, however,` also be used inthe construction of these partsif desired. Separate bottom 2 may be made of glass.

It is obvious that the embodiment of my invention described and shown inthe foregoing description and drawings is but a typical form thereof,and that many modifications and changes may be made in matters ofconstruction and arrangement of parts without departing from the spiritof the invention, and I do not mean to limiti myself to the speciiicform shown and described, but
